中子照相转换屏性能的对比测量

Contrastive measurement of neutron-radiography-convertor capability

简要介绍了采用带孔镉片为模拟被照物 ,检验国产 Gd2 O2 ( Tb)屏、金属钆屏、6L i FZn S( Ag)屏性能的对比测量实验。通过对实验图像的分析 ,认为金属钆屏分辨率优于 Gd2 O2 ( Tb)屏和 6L i FZn S( Ag)屏 ,6L i FZn S( Ag)屏反差灵敏度、照相速度优于 Gd2 O2 ( Tb)和金属钆屏。

The contrast measurement experiment of the capabilities of Gd 2O 2(Tb),Gd and 6LiFZnS(Ag) convertors made in China is described in this paper. The results that resolution of Gd convertor is better than that of Gd 2O 2(Tb) and 6LiFZnS(Ag) convertors, and the sensitivity and exposure time of 6LiFZnS(Ag) converors is better than those of Gd 2O 2(Tb) and Gd converts are given out through imaging analyse.
